Early diagnosis of Zollinger-Ellison syndrome (ZES) is crucial for surgical cure, as metastasis is a common cause of death. High suspicion is needed due to non-diagnostic gastrin levels in 50% of patients.

Area of Science:

  • Gastroenterology
  • Endocrinology
  • Surgical Oncology

Background:

  • Zollinger-Ellison syndrome (ZES) presents with peptic ulcer-like symptoms and marked gastric acid hypersecretion.
  • Metastasis is the primary cause of mortality in ZES patients.
  • Early diagnosis and surgical intervention are vital for potential cure.

Purpose of the Study:

  • To emphasize the importance of high clinical suspicion for diagnosing ZES.
  • To outline diagnostic strategies for ZES, especially when initial gastrin levels are inconclusive.
  • To guide management decisions based on disease stage and patient factors.

Main Methods:

  • Clinical observation and patient data analysis.
  • Review of diagnostic challenges, including provocative tests for gastrin levels.

  • Discussion of imaging techniques for tumor localization (CT, angiography, venous sampling).

    • Main Results:

    • Up to 50% of ZES patients may have non-diagnostic serum gastrin levels, necessitating provocative testing.
    • Antisecretory drugs are used to control acid hypersecretion.
    • Tumor localization may require advanced imaging and sampling techniques in difficult cases.

    Conclusions:

    • A high index of suspicion is essential for early ZES diagnosis.
    • Diagnostic workup should include provocative tests and advanced imaging when necessary.
    • Management should be tailored: avoid major surgery in MEN-I and metastatic cases; resect tumors if non-metastatic.
